Need help to create the structural system of a form

Hi,

I have a form (polysurface) and i want to make a parallel structural system for it using grasshopper.

I tried the "extrude" in the x direction, which gives thickness to my pieces but they aren't integrated to my form! Is there anybody who could help me solve my problem?

Thanks in advance

P.s. i attach you the files to be easy to have a look.
